How to use it?
- Express {x} in terms of y where:
- 15*x-5*y=-5
- 18*x+20*y=-2
- -5*x-6*y=-1
- -17*x-15*y=-17
- Equation:

The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$9 x = y + 6$$
Divide both parts of the equation by 9
We get the answer: x = 2/3 + y/9
9*x-1*y = 6
Looking for similar summands in the left part:
-y + 9*x = 6
Move the summands with the other variables
from left part to right part, we given:
$$9 x = y + 6$$
Divide both parts of the equation by 9
x = 6 + y / (9)
We get the answer: x = 2/3 + y/9

$$x_{1} = \frac{\operatorname{re}{\left(y\right)}}{9} + \frac{i \operatorname{im}{\left(y\right)}}{9} + \frac{2}{3}$$
x1 = re(y)/9 + i*im(y)/9 + 2/3
